Dear list,
I am trying to look at the function inside a package. I know that
methods() would do the trick, but what if the function is hidden? I have a
problem displaying the hidden function.
Say, for example the MCMC package. How do you view the code of that
function?
You can use the prefix MCMC:::foo to display the foo function from MCMC,
whether or not it is exported.

something like this:
which
function (x, arr.ind = FALSE, useNames = TRUE)
{
wh - .Internal(which(x))
if (arr.ind !is.null(d - dim(x)))
arrayInd(wh, d, dimnames(x), useNames = useNames)
else wh
}

Re: [R] how to view source code of a function inside a package?
This is R FAQ 7.40, and that document gives some good pointers:
http://cran.r-project.org/doc/FAQ/R-FAQ.html#How-do-I-access-the-source-code-for-a-function_003f
I prefer to simply download the source code version of the package
from CRAN, so that comments aren't stripped, but there are several
other options.

Re: [R] how to view source code of a function inside a package?
thanks all. The mcmc:::foo is exactly what I am looking for.

It might be a C code wrapped around.
